This number has called 3-4 times a week for the last month. doesn't leave a message. have blocked the number for the last three weeks and calls continue. obviously getting hung up on after the first ring by the call blocker isn't making an impression on this caller so it's either a large call center waiting for a live voice before picking up or a robocaller. after wasting their time for another 3 months, they'll finally move on. have to admit getting the call blocker is the best investment I've made in a while. Typically we get 8-9 scam calls a day and the call blocker suppresses the ring and handles all of them.
